Wesley, 25, is also facing seven other misdemeanors, including driving while intoxicated.

In May, 2011 Wesley was driving her Ford Explorer when it went off westbound Interstate 88 in the town of Fenton and into the Chenango River. There were four people in the Ford. She was the only survivor.

The bodies of 39-year-old Carri Michalski, 25-year-old Robert Moorehead and 45-year-old Robert Marshall were later recovered from the river.

Broome County Sgt. Kevin Mauser was first to take the witness stand Wednesday. He was working the night the crash happened, and was one of the first on the scene.

Inside the courtroom, Mauser pointed to Wesley and identified her as the driver of the vehicle. He said he could smell alcohol on her breath while interviewing her on the scene.

Mauser recovered evidence from the SUV that included several beer cans and an empty bottle of whiskey. He also took the court through photographic evidence of the scene.

A second witness for the prosecution testified that Wesley was at The Fireside Inn the night of the accident. She was seen with a mixed drink in her hand before they left the bar.

Wesley was released on her own recognizance following an arraignment late last year.

She was seen leaving the courthouse on Wednesday with her mother. The trial will continue Thursday at the Broome County Courthouse.
